Q:What USA reverse thread called
by|Apr 29, 2023
1 Answer
Answer This Question

A:  Hello, couplings that include a reverse thread are called 'Left-Right' Couplings; this reverse thread will allow you to couple pipes and nipples in a pre-existing plumbing line. We hope this helps with your project.

    Q:is this a left right coupling
    by|Dec 29, 2021
    3 Answers
    Answer This Question

    A:  This is a standard coupler. When a pipe is inserted from either end it will turn clock-wise to tighten. The coupler you're describing would be a specialty item - not something typically seen off-the-shelf and will clearly state "left & right threads."

    by|Dec 30, 2021

      A:  Not sure what you mean. It's used to connect 2 shorter lengths of pipe together to get 1 longer length. At each end you would turn the pipe to the right to tighten it.

        A:  Hi shan, this is not a Left-Right coupling, as if it was the product title would call it out as either, 'Left-Right' or 'LR'. We hope this helps with your project.

          Q:can you mig weld this material?

          Answer This Question

          A:  Hi Donny, for that question we recommend checking either local plumbing code or a local welder for guidance on your project need. There's too much we don't know about your specific project and therefore cannot give you firm recommendations above & beyond how this is designed to connect.

              These are a Chinese Product
              The photos are inaccurate and do not show that there is CHINA written largely in all capital letters on one side of them. If you’ll be using these for furniture i’d steer away unless you want your project to say china all over it.
